This todo is for people working on fpc to write down what they want to do till 2.2.2 is released. It's not a wishlist what shall be done. Feature requests etc. should be added to mantis.


  • Document changes potentially affecting currently working code to User_Changes_2.2.2 (all)
    • Document regcal stack parameter order change
    • Document val change regarding the handling of #0
  • Fix bugs with target 2.2.2


  • packages (Florian/Peter) (2.4.0)
  • Module handling rewrite (Peter/Florian) (2.4.0)
  • Crosscompiling to Mac OS X (Marco, been done, but not end user ready ->2.4.0)
  • rewrite assigning of automated types like variants and widestrings (Florian)
  • complete unique type support (Florian)
  • dispinterfaces (Florian)
  • improve HTML rendering of IDE (Florian/Tomas(?))
  • Internal linker for ELF platforms? (2.4.0)
  • better string append support (Peter)
  • Use Sysutils (Peter)
  • Directory caching (Peter)
  • All path/filename handling in the compiler ansistring. (Thomas)
  • generics support (Florian)
  • PIC support for Darwin/ppc and Darwin/i386 and compile rtl, packages and fcl with PIC support because non-PIC dynamic libraries are unsupported (although they work in simple situations) (Jonas)
  • Fix all testsuite failures which are in 2.1.x but not in 2.0.x (all)
  • bug fixing (all)
    • Delphi incompatibility regarding register calling convention (push order of stack based arguments) (Florian)
    • fix bugs in *nix's (joining detached threads, possibly some more dataraces) (Jonas)
  • Binary writer generates incorrect debug info, for example enums do not show. (Peter)
  • Ansistrings/widestrings should show in gdb as string, not address. We can achieve this by emitting debug information for zero terminated strings.
  • Fix -pg gprof support.


  • Use fpmake for building (Michael/Peter)
  • Use fppkg for package repository (Michael/Peter)
  • get an initial set of packages for often used pkgs. (during RC'ing?)


  • 64-bit file support for Solaris (?)
  • 64-bit file support for MacOS (?)
  • 64-bit file support for Netwlibc (?)
  • 64-bit file support for Linux (Neli)
  • 64-bit file support for Linux/FPC_USE_LIBC (Neli, bug 7987)
  • Fix get_caller_frame stuff for code without stackframes (Jonas)
  • ARM badly needs mod/divide helpers in assembler
  • add {$optimization nostackframe} to objects unit and to all code which uses it (IDE, fvision) (superseded by r5146)
  • basic template unit (map and list) (Neli)
  • TFormatSettings (bug 6242). (Marco/Michael)
  • Make decision about threading in Linux (NTPL, unit libc) (bug 6280) (???, Marco is willing to help with the implementation)
  • bug 7247 (TStringList incompat, Marco/Michael. Scheduled fro XMas week)
  • bug 6824 (stored=false property storage, Lazarus angles?)
  • bug 7947 (Syncobjs cleanup)
  • properly scan and clean up sockets on all platforms (Ales)
  • fix internal ThreadManager inconsistencies (Ales?, March 31? - probably not)
  • Make declarations in Windows unit for WinCE compatible with those in the windows unit for Win32. (Yury)


  • DB: Restructure the db-testsuite (Joost)
  • DB: bufdataset: implement calculated fields (Joost)
  • DB: bufdataset: implement in-memory-filtering (Joost)
  • DB: bufdataset: make it possible to use bufdataset directly, thus not only it's descendents. (like TClientDataset) (Joost)
  • DB: bufdataset: save and read datapackets as XML (Joost)
  • DB: sqldb: improve speed by fetching more then one record at a time (Joost)
  • DB: sqldb: add the ability to make plugins (Joost)
  • DB: sqldb: a backup and restore plugin for firebird (Joost)
  • DB: sqldb: revise the TSQLScript component (2.4.0 ? Joost)
  • If possible: set up a test-suite for the fcl, like the db-testsuite. In such a way thet it can be used automatically, just like the compiler test-suite (Joost)


  • Try to implement a TP like evaluate/modify window (Daniel)
  • Check and modify compile options window to reflect all new 2.2 compiler options.


  • Update runtime error list.
